    @AntonMcGowan7 @O2 @_jamiemcbrearty I am tired of topping up and not being in the tariff that the package had said and not applicable to O2 fail their security and be told that by account is blocked. Don't understand #metoo

  • RobCarey8 Rob Carey (@RobCarey8) reported

    @O2 13.4% rise from April. Thank god my contract is up this year. I will definitely be signing off as an O2 customer after many, many years. Fairness should be at the heart of any business model, whereas greed will tell on the business in time. Goodbye O2........

    @wendypajak @O2 @wendypajak it’s because you are pay your bills a month in advance and O2 needs 30 days notice to disconnect the line completely if you can’t wait 30 days request your PAC by texting PAC to 65075 to move your number to a different network and within 1 working day.
